The second 2017 exclusive from the LEGO Group to be available at San Diego Comic Con has been announced, a BrickHeadz twin pack containing Supergirl and Martian Manhunter.

ComicBook.com exclusively revealed the DC Comics based set, following yesterday’s reveal of the exclusive Marvel Spider-Man and Venom set. Supergirl and Martian Manhunter clicks in at 234 pieces, priced at $40.00.

There are instructions to be followed for fans looking to pick up the set:

Now, while you will eventually buy it from the LEGO booth, you will need to first visit the Pavillion Terrace to enter a random drawing to qualify first, which will start around 6 a.m. If your ticket is picked you can then purchase the set from July 21st to July 23rd.

If you can’t purchase it at the show there will be a chance to win the set on Twitter by following @LEGO_Group and the hashtag #LEGOSDCC.
